How to Improve the Fire Resistance Limit of the Curtain Wall and Extend the Fire Resistance Time of the Curtain Wall? -WJW Aluminum Supplier Aluminum

The building glass curtain wall is favored by architectural designers with its beautiful appearance, good lighting, and delicate texture. However, the complex and beautiful design of the building curtain wall will also have a negative impact on fire safety.

Fire and resistance are the category of passive fire protection, corresponding to the more common active fire extinguishing (including spray, detectors, etc.). . It refers to a building with fire -resistant sealing materials (products), especially the firewall, pipeline well, strong, and weak bridge framework of high -rise buildings. In order to control the fire situation and reduce the loss of fire, it is necessary to use a certain fire time effect or easily form a crack like chimney (including the seams of the curtain wall or the connection of the fire wall wall, etc.) to block the holes. ), So that the fire source will not wear to other fire areas or other floors to control the fire and reduce the loss of the fire. Generally speaking, it includes the detailed structure of various penetration walls, the floor of the floor and the treatment of various structural nodes.

How to increase the fire resistance limit of the curtain wall, extend the fire resistance time of the curtain wall, and maximize the loss of the losses caused by the fire is a problem that must be considered in the design and application of the curtain wall. However, it is impossible to estimate or calculate which construction plans are more reasonable to meet how long fire prevention requirements can be achieved. The design must be carried out according to the relevant data obtained by the relevant test.

STI glass curtain wall layer indirect sewing fire prevention and sealing method

STI (SpecifiedTechnologySinc.) Has always paid attention to and is committed to the development of fire prevention and blocking technology. It is in a leading position in the same industry. Especially for the indirect sewing construction plan for glass curtain walls is the most important solution in the industry.

STI fire prevention sealing method of glass curtain wall layer is mainly to cover the ore cotton filling gap and spray glue to cover the mines to form a system of high smoke and high fire resistance. The refractory resistance is as follows:

1. When the total width of 64kg/m3 is 125%150%, the mines in the gap in the gap are tightly filled, so that the mineral cotton in the gap has sufficient pre -pressure. On the other hand, the squeezing filling is more dense. For a large gap (250mm), the tightness of the mine cotton and the floor can be improved by adding corner steel or fasteners.

2. Special formula spray glue is carbonized into fine particles in the fire, covered with mineral cotton, fills small holes on the surface of mineral cotton, so that the carbide layer and mineral cotton are formed to form a smoke -proof and fire -proof zone. This is completely different from the traditional sealing principle of the supporting plate with galvanized steel plates. The traditional galvanized steel plate will swell after the fire, causing a greater opening hole and leading to the spread of smoke.

3. By setting an anchoring nail (pulse nail), the isolation area of the relevant construction method is fixed on the back panel or corner steel that has nothing to do with the curtain wall structure. Even if the lower curtain wall frame is melted, the isolation area can still maintain the overall to avoid the fire of the fire from moving upward. Essence
